摘　　要：为探索混合硝酸酯增塑的聚醚聚氨酯黏合剂体系的新型发射药的燃烧性能,通过密闭爆发器常规实验和高压实验,研究分析了JM Z发射药在不同压力范围的燃烧特性。结果表明,JM Z发射药在低压下的燃速压力指数较大,具有高含量RDX硝胺发射药的共同特征,但在高压下的燃速压力指数逐渐变小,与制式发射药相当,在燃速压力指数的变化过程中不存在明显的转折现象。另外,JM Z发射药在起始阶段表现出了良好的燃烧渐增性,对身管武器的应用是十分有利的。In order to search the combustion performance of a new propellant with polyether polyurethane binder plastized by mixed nitrate ester, the combustion characteristic of the JMZ propellant in the range of different pressure was researched by closed bomb normal test and high pressure test. The test results showed that burning rate pressure exponent values of the JMZ propellant are large at low pressure, as those of RDX nitramine propellants, but the burning rate pressure exponent values gradually diminish along with increase of pressure and are equivalent to those of conventional propellants at high pressure. There are no obvious turning phenomena in course of the change of burning rate pressure exponent values. In addition, according to the test results, the JMZ propellant revealed a good burning progressive in initial stage which should be beneficial for barrel weapon.
